 9. The apparatus for data quality management and control according to claim 8, wherein, the program codes further cause the processor to: analyze an importance degree of each datasheet according to the current record information and the pieces of history information, the more the datasheet flow information corresponding to the datasheet name, the higher the importance degree of the datasheet.
 10. The apparatus for data quality management and control according to claim 9, wherein the program codes further cause the processor to: set a datasheet collecting rule, and collect a plurality of datasheets from the data center according to the datasheet collecting rule; determine whether names of any two datasheets in the plurality of the datasheets are the same, if the names of the two datasheets are the same, then determine whether contents of the two datasheets are the same; if the contents of the two datasheets are the same, then transmit a first deleting command to the data center to enable the data center to delete any one of the two datasheets; if the contents of the two datasheets are different, then acquire timestamps of the two datasheets from the data center, and transmit a second deleting command to the data center to enable the data center to delete a datasheet having a smaller timestamp in the two datasheets.
